ssd and increased download speed

[pinn]

Hi,

I had been using mechanical drives for a while and sab used to show this was the limiting factor in my download speed. As an aside, has that facility gone as can't find anymore? I have upgraded to a usb 3.0 ssd and when I test in the UI it shows download folder at 104.1 MB/s and my download speed at 60.9 MB/s but doing the test download I'm stil capping out at about 48MB/s which is about the same as without the ssd. Is system performance in fact the limiting factor and not the temp folder?

probably yes: system performance pystone 70.000 is quite low.

cheers sander. I guess it will be faster at unpacking at least.

Your screenshot says:
* "osmc", so OSMC (Open Source Media Center)?
* aarch64 ... so ... Raspi? Or ... ?

Yes, it's OSMC on Vero V https://osmc.tv/vero/

Yes, it's OSMC on Vero V https://osmc.tv/vero/

Your Vero V (Tech Specs)
Quad Core 2Ghz ARM 64-bit processor (S905X4-O)

... with the S905X4 from 2020 or so.

So you mean I'm getting as much mileage out of it that's possible then, really?

One cannot hard-calculate what the speed can be, but I would say 48MB/s is quite nice for that hardware.

If you want to find out if you can squeeze aout a few more MB/s, read https://sabnzbd.org/wiki/advanced/highspeed-downloading

Thanks Sander. I've already tweaked all I can from there. Your input is appreciated.

Probably yes, the amlogic chipsets in devices such as yours are optimized for use as media players. I have a similar box running coreelec/kodi here using a slightly older, passsively cooled s905x3 chipset. They do hardware decoding of common media formats making them incredibly efficient at that, despite their very modest performance as a generic CPU. Chipset design often limits them further, for example by sharing bandwidth between usb/wifi/ethernet (in ways similar to some raspberry pis models).

SABnzbd's Download Speed Tests & Limiting Factors
1. Has the "limiting factor" info been removed?
You're right — SABnzbd used to show limiting factors more clearly in the Status page, like "Disk too slow" or "CPU limited." In recent versions, that specific line isn’t always present, especially if no bottleneck is clearly detected. Instead:

It now shows things like:

"Download speed"

"Disk performance"

"Download folder test" speed

But may not call out a limiting factor explicitly unless there's a clear constraint or error
